Application filed January 12,1912; Serial No. 670,836.

lump fuel is fed in through the distributers.

' by means of a jet or blast of steam or other October 2, 1911. One ofthe objects of this present inven-- fluid under pressure as set forth inour prior application Ser. No. 652,462, filed tion is to provide animproved form of distributer having a wide shield-like extension at thetop beyond the open end and having deflecting ribs or surfaces fordistributing the fuel throughout the length of the firebox. 25

This form is especially desired for use at the sides of the furnace.

Another object is toprevent to a large'extent, the warping of thedistributers due distributers. I

In the accompanying drawings: Figure 1 is a plan of one form of-ourimproved,d1s-- tributing device; Fig. 2, a longitudinal section of same;Fig. 3, a plan with a portion in horizontal section, showing a slightmodification; Fig. 4, a longitudinal section of the same, a portion ofthe elbow being 'shown in elevation; Fig. 5, an inside ,end View; Fig.6, anoutside end view of, the distributor shown in Figs. 3 and 4; andFig. 7, minside end view of the distributer shown in Figs. 1 and 2.

According to the. construction shown in- -the drawings, the improvementis illustrated as applied in connection with that type of distributerhaving a cylindrical body, 19, adapted to be-inserted from within thefurnace through the opening, 21, in the furnace 50.

. ably connected to the elbow, 19*, on the out wall, or water leg of thethe box, and detachside of the boiler, the elbow having connections forfuel supply, an air inlet-opening,

shield 23.

I 27 and a fluid pressure blast, 28, all as set v When used as sidedistributers, as in the.

present instance, it is desired that the 'fuel should be evenlydistributed through the length of the fire box and to thefar'corners,and for this purpose the inner end of the distribute!" may be formed, atthe top with a broad flaring hood .or shield-like en. tension, 23,projecting beyond the fuel dis:

24, "for diverting the fuel upward at this point against. the undersurface. of the has Y chargeopening, 22, and as shown, .thennder' Asshown inv Figs. 3, 4, and 5, the-lateral. I

extension ofthe shield is principally at one s1de of the center line ofthe distributer, and 1n this case a deflecting-rib, .26, is"10-' catedon the underside of the shield for dlvertmg a portion of the fuel towardthe middle portion of thefurnacegra'te.

For the purpose of preventing the warping of the broad extension shieldor hood,

23, dueto the high temperature to which it is exposed in the furnace,thelongitudinally diverging ribs, 29, are provided. on the .to'poftheshield. Asthe sidedistributers are usually de signed to receivetheir fuel supply through inclined pipes, the elbow I portion, '19; ispreferably turned at an angle to the vertical, as shown moreparticularly in Fig. 6. As the fuel is-driven'through the distrihuter bythe steam: blast, it is deflected up ward by the wedge projection 24 atthe discharge opening and impinges againstthe under side of the shield,23, from which it is spreadout laterally and distributed over a widerange of grate area throughout the length of. the fire box,
